I thought he was joking? I hope nobody would use acetone! LOL
Best,

I'm not sure what the formulation was in the past but denatured alcohol
just just acetone? it works the best anyways.
nowadays is just ethanol with maybe 5-10%
methanol added. You definitely
shouldn't be drinking it (in vivo, methanol is metabolized to formaldehyde
via oxidative reduction - formaldehyde attacks the optic nerve - which is
why drinking wood methanol makes you go blind) but other than that, I
wouldn't say it's particularly more harmful to you, boards or components
than isopropanol is. You wouldn't want to drink that, either!
Wikpedia references EU Regulation 162/2013, which gives the various
recipes
across the EU:

OJ:L:2013:049:0055:0061:EN:PDF
Taking a random sample from a few different countries, the basic recipe
seems to be 1% mixed crud to make it unpalatable, up to 10% methanol, and
the rest ethanol. The ethanol and methanol will evaporate readily enough,
but I'd be somewhat concerned about residue left from non-volatile
components of the 1%.
It's not like isopropanol is terribly expensive or difficult to get hold
of. I can order ten litres of it from Amazon ?28.66 with free delivery.
If anything, it seems to be slightly cheaper than meths.
